Une source de puissance de la machine de forage à tuyau de frottement (2) est un composant de puissance pour l'équipement d'excavation de terre (1). La machine de forage à tuyau de frottement (2) est installée sur le corps d'un équipement d'excavation de terre par l'intermédiaire d'une base d'interface (21). Un châssis (22) de la machine de forage à tuyau de frottement (2) comporte une plateforme de pression (221). La base d'interface (21) comprend un bloc de pression. Quand la machine de forage à tuyau de frottement (2) appuie sur un fût de protection, le châssis (22) est élevé et tourne d'un seul tenant par rapport à la base d'interface (21). Après une rotation d'un angle prédéterminé, le bloc de pression et la plateforme de pression (222) sont maintenus contre le châssis (22) de façon à limiter un plus ample mouvement du châssis (22). La base d'interface (21) et l'équipement d'excavation de terre (1) sont reliés de façon fixe, et, par conséquent, ne peuvent pas tourner, le poids de l'équipement d'excavation de terre (1) empêchant une plus ample élévation du châssis (22). L'équipement d'excavation de terre remplace le contrepoids de la machine de forage à tuyau de frottement (2), de façon à réduire ainsi les coûts de construction.
